摘要/Abstract

摘要： 行走轮作为采煤机行走装置的执行机构,由于受强冲击载荷作用常发生断齿事故,严重影响工作效率,且威胁到操作人员人身安全。首先阐述了行走轮磨损、断齿、剥落和齿面塑性变形等失效形式;之后针对断齿失效,总结了优化产品设计、合理选择材料、增加齿轮模数、安装保护装置和热处理工艺优化等应对策略;最后,提出将传统渗碳淬火工艺与Q-P-T工艺相结合对行走轮进行热处理来提高其强韧性的建议。

Abstract: Walking wheel, as the actuator of the walking device of the coal mining machine, often suffers from tooth breakage accidents due to the effect of strong impact loads. This seriously affects the working efficiency and poses a threat to the personal safety of the operators. Thus firstly, the failure modes of the walking wheel, such as wear, tooth breakage, spalling and plastic deformation of the tooth surface were expounded. Subsequently, for the tooth breakage failure, the coping strategies were summarized, including optimizing the product design, rationally selecting materials, increasing the gear modulus, installing protective devices and optimizing the heat treatment process. Finally, the suggestion of combining traditional carburizing and quenching processes with Q-P-T processes was proposed for heat treatment of walking wheel to improve its strength and toughness.
